Error When Installing with a Non-Admin Account

You may encounter an error such as the following (or with similar wording) if you are not an Administrator when executing the MSI installer file. 
The system administrator has set policies to prevent this installation.

These error messages are due to not having permissions to install an MSI package as a non-admin account. Other than logging in as an administrator to install Connect, you may also ask that your Administrator grant the group policy access for non-admin users to install applications.

The following example shows you how to grant group policy access for non-admins to install software on Windows 2016:

  1. Launch the Microsoft Management Console (MMC).

    Go to Start menu > Run. Enter mmc and click OK to launch it.

  2. Add the Group Policy Object Editor Snap-in.
    1. In the MMC, go to the toolbar and select File > Add/Remove Snap-in:

    2. In the Add or Remove Snap-ins window, select the Group Policy Object Editor and click Add:

    3. In the Select Group Policy Object window (wizard), under Group Policy Object, click Browse and select either This Computer or specify another computer. When done, click OK to return to the wizard window.
    4. In the wizard window, click Finish. When you are returned to the Add/Remove Snap-ins window, click OK to save the changes.
  3. Grant the Windows installation group policy.
    1. In the MMC, navigate into Console Root > Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components and locate Windows Installer:

    2. Double-click Windows Installer.
    3. In the list that appears, locate Turn off Windows Installer and double-click it.
    4. The Turn Off Windows Installer window opens.
    5. Under the Turn off Windows Installer heading, select Enabled. In the Disable Windows Installer box, open the pull-down and select Never. When finished, click OK:

    6. To close the MMC, click File > Exit.
    7. When prompted to save console settings, click Yes to save the settings to a file. When prompted for a .msc filename, click Save.
    8. Reboot the computer to apply the changes, or execute the following command at a command prompt:
      > gpupdate /force
